Abstract

A study to determine the water quality changes between run-off water and rainwater was carried out at two different location, Kajang town and Bangi (Universiti Kebangsaan Malaysia). The objective  of this studies was to determine whether run-off water could be used as an indicator for urban pollution. Ten and three sampling stations has been chosen at Kajang and Bangi respectively. A number of selected water quality parameters particularly for those that are use in determining the Water Quality Index (WQI) and a few other parameters consisting nutrients, metals and in- situ parameters were analysed using methods as suggested by American Public Health Association (APHA) and Global Environmental Monitoring System (GEMS). Results obtained show that there are an incremental values for most of parameters studied in run-off water compare to rainwater. As a conclusion, run-off water may be  used  as a sole parameter to determine whether the area has been polluted or not.
